Tax Man lien-ing on Robin Thicke, Paula Patton

Couple Deep in Debt

Celebrity couple Robin Thicke and Paula Patton have found themselves on the wrong side of an IRS lien. The federal government claims the singer and his actress wife failed to pay nearly $500,000 in taxes between 2009 and 2010.

The handsome couple -- one an actress, the other a "blue-eyed soul" crooner -- forgot to save a slice of their financial pie for the federal government. Now the Internal Revenue Service (IRS) has come calling.

Tax officials say Robin and Paula, who wed in 2005, failed to pony up dough in 2009 and 2010. The oversight has left the award-winning Thicke and Patton -- who earned critical acclaim for her role in the 2009 hit Precious -- shamefaced as their California property was slapped with a lien this month.

According to official documents filed in Los Angeles last week, the couple owes the Feds $492,583.49 in back taxes. It is a debt the twosome is determined to settle, according to their camp.

"They've already paid more than half of this and they're working with the IRS to pay the rest," a rep for Robin and Paula said over the weekend.
